Constructor Detail

IlrVariable

public IlrVariable(String name,
                   IlrValue value)

Constructs a variable binding.

Parameters:

name - The name of the variable.

value - The value to which the variable is bound.

IlrVariable

public IlrVariable(IlrReflect reflect,
                   String definitionName,
                   Class type)

Constructs a variable binding.

Parameters:

reflect - A reflect.

definitionName - The name of the variable.

type - The type to which the variable is bound.

IlrVariable

public IlrVariable(String definitionName,
                   IlrType type)

Constructs a variable binding.

Parameters:

definitionName - The name of the variable.

type - The type to which the variable is bound.

Method Detail

getName

public String getName()

Gets the name of the variable.

Returns:

The name of the variable.

getShortName

public String getShortName()

Gets the short name of the variable

Returns:

the short name of the variable

setName

public void setName(String name)

Sets the name of the variable.

Parameters:

name - The new name of the variable.

getValue

public IlrValue getValue()

Gets the value of the variable.

Returns:

The value of the variable.

setValue

public void setValue(IlrValue value)

Sets the value of the variable.

Parameters:

value - The new value of the variable.

isAssignableFrom

public boolean isAssignableFrom(IlrValue value)

Checks whether the value value can be assigned to the variable.

Specified by:

isAssignableFrom in interface IlrAssignable

Parameters:

value - The value assigned to the expression.

Returns:

true is the value value can be assigned to the variable, false otherwise.

isEventCondition

public boolean isEventCondition()

Description copied from class: IlrValue

Returns whether this value is, or is bound to, the result of a condition, and this condition is an event condition.

Overrides:

isEventCondition in class IlrValue

Returns:

true if this value is, or is bound to, the result of an event condition, and false otherwise.

exploreValue

public Object exploreValue(IlrFactoryExplorer explorer)

This method explores the variable using a factory explorer.

Specified by:

exploreValue in class IlrValue

Parameters:

explorer - The factory explorer.

Returns:

An object, the result of the exploration, or null if the method does not return a value.

exploreAssignable

public Object exploreAssignable(IlrFactoryExplorer explorer)

This method explores the variable using a factory explorer. In this case, the variable is an assignable object.

Specified by:

exploreAssignable in interface IlrAssignable

Parameters:

explorer - The factory explorer.

Returns:

An object, the result of the exploration, or null if the method does not return a value.

getPackage

public IlrPackageFactory getPackage()

Returns the package in which the variable is defined in case this variable models a package variable. Otherwise it returns null.

Returns:

The package in which the variable is defined.
